Does anyone know if they are really sticking to the purchase after March 1, 2012 rule? I have someone willing to give me a car seat UPC, but it was purchased before that. I'm also looking for a carrier UPC, but I figure I will buy one and either try to sell it or give it to someone who needs it if I have to. If I can't use that car seat UPC, then I will still be looking for one of those.
Why don't you compare the UPC to the one on the drop-down menu for Britax Registry Rewards? I think as long as it matches they have no way to know when it was purchased. The UPC is not unique for each individual purchase. The UPC is the identifier code for a particular product, but not the individual purchaser. I know that my Britax carrier had a DOM that was early 2011 and I was worried it might not qualify even though I just bought it last week. Nope, the UPC did match the one listed and it qualified.
